Perhaps the strangest thing about the #whining critique of Trump, though, is that he appeared to boast, in a CNN interview last year, that it is a positive character trait. “That’s right, I am the most fabulous whiner — I do whine, because I want to win, and I’m not happy if I’m not winning,” Trump told Chris Cuomo in August, 2015.
“I am a whiner, and I keep whining and whining until I win,” Trump added.
